Subject: [PATCH] arm64: dts: amlogic: meson-sm1-odroid-hc4: fix active fan thermal trip
Git-commit: 1d2f14117aa7773efff50f832b85fc7779e586e0
Patch-mainline: v6.3-rc1
References: git-fixes

Add an active trip tied to the on-board fan cooling device, which is better
than describing it along the passive cooling maps.
